 Hi, everybody. I'm Jack Hanna. Since I was a boy, I've been fascinated with animals, especially their tireless work ethic. Just look at birds who gather supplies to build nests or penguins who travel up to 500 miles to secure food for their families. This work ethic is shared by our best friends, canines who perform life-saving work every day. Dogs comfort returning veterans. They work with diabetics, alerting them when there's a change in their blood chemistry. Working dogs are valuable in many ways. So please join me and American Humane in supporting our heroic working dogs. Go to AmericanHumane.org to learn more.
